2008-01-29[MIPS] remove unneeded button check for resetYoichi Yuasa
Removed unneeded button check for reset. Because, the Cobalt has power switch. Signed-off-by: Yoichi Yuasa <yoichi_yuasa@tripeaks.co.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-01-29[MIPS] move vr41xx_calculate_clock_frequency() to plat_time_init()Yoichi Yuasa

2008-01-29[MIPS] Altas, Malta: Switch boot file format to raw.Ralf Baechle
A raw binary boots about twice as fast as SREC. The possibility to generate SREC binaries remains by simply using the vmlinux.srec target but seems only useful for the probably hypothetical case where one of these systems is booted over a serial interface.

2008-01-29[MIPS] Extend performance counter event field.Ralf Baechle

2008-01-29[MIPS] RM: Collected changesThomas Bogendoerfer
- EISA support for non PCI RMs (RM200 and RM400-xxx). The major part is the splitting of the EISA and onboard ISA of the RM200, which makes the EISA bus on the RM200 look like on other RMs. - 64bit kernel support - system type detection is now common for big and little endian - moved sniprom code to arch/mips/fw - added call_o32 function to arch/mips/fw/lib, which uses a private stack for calling prom functions - fix problem with ISA interrupts, which makes using PIT clockevent possible Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-01-29[MIPS] Alchemy: Au1210/Au1250 CPU supportManuel Lauss
This patch adds IDs for new Au1200 variants: Au1210 and Au1250. They are essentially identical to the Au1200 except for the Au1210 which has a different SoC-ID in the PRId register [bits 31:24]. The Au1250 is a "Au1200 V0.2". Signed-off-by: Manuel Lauss <mano@roarinelk.homelinux.net> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2008-01-29[MIPS] Eleminate local symbols from the symbol table.Ralf Baechle
These symbols appear in oprofile output, stacktraces and similar but only make the output harder to read. Many identical symbol names such as "both_aligned" were also being used in multiple source files making it impossible to see which file actually was meant. So let's get rid of them.

2008-01-29[MIPS] IP28: added cache barrier to assembly routinesThomas Bogendoerfer
IP28 needs special treatment to avoid speculative accesses. gcc takes care for .c code, but for assembly code we need to do it manually. This is taken from Peter Fuersts IP28 patches. Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2008-01-29[MIPS] R4000/R4400 daddiu erratum workaroundMaciej W. Rozycki
This complements the generic R4000/R4400 errata workaround code and adds bits for the daddiu problem. In most places it just modifies handwritten assembly code so that the assembler is allowed to use a temporary register as daddiu may now be treated as a macro that expands to a sequence of li and daddu. It is the AT register or, where AT is unavailable or used explicitly for another purpose, an explicitly-named register is selected, using the .set at=<reg> feature added recently to gas. This feature is only used if CONFIG_CPU_DADDI_WORKAROUNDS has been set, so if the workaround remains disabled, the required version of binutils stays unchanged. Similarly, daddiu instructions put in branch delay slots in noreorder fragments are now taken out of them and the assembler is allowed to reorder them itself as possible (which it does making the whole idea of scheduling them into delay slots manually questionable). Also in the very few places where such a simple conversion was not possible, a handcoded longer sequence is implemented. Other than that there are changes to code responsible for building the TLB fault and page clear/copy handlers to avoid daddiu as appropriate. These are only effective if the erratum is verified to be present at the run time. Finally there is a trivial update to __delay(), because it uses daddiu in a branch delay slot.

2008-01-29[MIPS] R4000/R4400 errata workaroundsMaciej W. Rozycki
This is the gereric part of R4000/R4400 errata workarounds. They include compiler and assembler support as well as some source code modifications to address the problems with some combinations of multiply/divide+shift instructions as well as the daddi and daddiu instructions. Changes included are as follows: 1. New Kconfig options to select workarounds by platforms as necessary. 2. Arch top-level Makefile to pass necessary options to the compiler; also incompatible configurations are detected (-mno-sym32 unsupported as horribly intrusive for little gain). 3. Bug detection updated and shuffled -- the multiply/divide+shift problem is lethal enough that if not worked around it makes the kernel crash in time_init() because of a division by zero; the daddiu erratum might also trigger early potentially, though I have not observed it. On the other hand the daddi detection code requires the exception subsystem to have been initialised (and is there mainly for information). 4. r4k_daddiu_bug() added so that the existence of the erratum can be queried by code at the run time as necessary; useful for generated code like TLB fault and copy/clear page handlers. 5. __udelay() updated as it uses multiplication in inline assembly. Note that -mdaddi requires modified toolchain (which has been maintained by myself and available from my site for ~4years now -- versions covered are GCC 2.95.4 - 4.1.2 and binutils from 2.13 onwards). The -mfix-r4000 and -mfix-r4400 have been standard for a while though. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
